You may not like this series in the first 3-4 episodes, I literally felt like dumping this anime in the middle, but i don't know what kept me going. The series is very horribly structured that is the main issue with this anime.
The character designs are pretty good, considering the double personality of Saya, it has been created in a very distinct manner. The demon side of her and the cute and kind personality of her, other character design are fine as well, but since i am writing this in 2016, there is a great graphic difference, so don't expect the anime t be that great in visual designs.
The sounds are okay, okay. Not the best once again. I myself have downloaded the highest quality (8-Bit audio system) and watched it but then again, the sounds could have been better, the opening song is good as well.
The story is the main issue where it falls behind, or otherwise this anime would have an average of like 7-7.5 which would be really great. As i had mentioned before the story writer of the anime is not the best. In the middle of the anime is gets interesting and gives you the urge to keep on watching but at the end you would think to yourself why did i spend son much time watching this series. Yes trust me i had felt this as well. But if you are the kind of person that does not care about stupid endings then this is fine for you.
Overall this is a good anime for a person, who has run out of animes to watch. So i don't highly recommend this anime to you, but if you want a change from all those "Slice of Life Animes" then this would be good for you. But get ready to face a lot of Gory, Sadness and Betrayl.
